' ALetters Patent No. 102,7 66, dated May 10, 1870.

IMPROVEMEN T IN PENCILSHARPENERS.

The Schedule referred to in these Letters Patent and making part cf th:same.

and

It consists of a cylinder, or other suitably-shaped block of wood ormetal, which is out beveling on one side only. l y

A holeis made longitudinally through the block, through which the pencilis thrust. A loosely revolving spring is arranged about the hole, whichclasps the pencil and allows it to revolve inside the block.

- A knife is-used to sharpen the pencil, the bevel of the block guidingit in cutting the wood and sharpening the point.

In order to niore fully illustrate and explain my invention, referenceis had to the accompanying drawings forming a part of thisspecilication, in which- Figure l is a side View.

Figure 2 is a longitudinal section.

A represents a cylindrical or other shaped block of wood, metal, hardrubber, or other suitable material, having sufficient solidity toprevent the sharp blade of a knifefrom readily cutting it. l

This block of wood or other material isperforated,

longitudinally, with a hole, a, which is of snfcient diameter to .easilyadmit the largest size of pencil or crayon Wbichvit may be necessary ordesired to sharpen.

Inside Vof the hole ,-at any convenient point, I placea loosely movingclasp-spring, b, shown at lig. 2. In the present instance, this springconsists of' a small roll of spring metal, havinga flange at each end,which confines it inside of a small chamber. lhis chamber is grooved outaround the holea of just suf-l icient width to admit the spring andallow it to move freely around. f

The spring must be capable of expansion, so as to admit the differentsizes `of pencils and clasp each firmly, so as to cause them both toturn in conjunction inside the ,cylinder or other block A.

The block A is beveled o on one side, e, soasto furnish a guide for theAknife in giving a regularv and proper taper to. the point of thepencil, which is turned in the block by the lingers to present itsdifferent sides to the knife'iu succession. l

The device is cheap, useful, and convenient, and can ybe used by anypersons, even children.

Having thus described my invention,

What I claim, and desire to secure by Letters Patent, is

.1. ,The beveled cylinder or block A, with its central hole a,substantially as and for the vpurpose above described.

v 2. In combination with the beveled .cylinder or block A, perforated asdescribed, the loosely revolving extensible clasp-spring l), for thepurpose set forth In witness whereof I -have hereunto set my hand andseal.
